Description

Electric switch for automobiles Bh-SPELLING

The invention relates to an electrical switch for motor vehicles according to the preamble of Main claim.

Such switches are preferably used for switching on motorized two-wheeled vehicles the brake light when the handbrake or footbrake is pressed, but also for switching other circuits.

There are known designs in which the connections in the carrier, which is usually made of plastic be poured. This method is very complex and prone to failure because the connections are made with great accuracy must be manufactured and inserted individually by hand into the injection molding machine. Next are remarks known, in which the connections are snapped into recesses in the carrier. Such a fastening but does not hold the relatively high forces when plugging and unplugging the flat plug attached to the cable was standing. A partially applied additional caulking is again time-consuming.

The invention is therefore based on the object of proposing a switch in which the production of the parts and the assembly is simple and at the same time ensures that the connections are securely fastened in the carrier is.

The object is achieved according to the invention in that the carrier has a central part and for each connection has a flap connected by two film hinges and that between the two parts one of the contour and Thickness of the middle piece of the connection remains free in which it is received.

Has a preferred embodiment of the invention a pin on the flap which extends through a bore of the connector in the central part. In a further embodiment, the pin is designed as part of a snap connection and locks into place a corresponding recess in the middle part.

The following description of an exemplary embodiment is used together with the drawings for more detailed information Explanation:

Show it

Figure 1 is a view of the switch, partially cut away;

FIG. 2 shows a three-dimensional representation of the carrier with a protruding flap and the connection.

In a housing (1), for example by means of a Thread (2) can be screwed into the handlebar fitting, not shown, of a motorized two-wheeler, an axially displaceable pin (3) made of insulating material is mounted with a collar (4) and an extension (5), on which an annular contact part (6) and a spring (7) are centered.

This is supported on the one hand on the contact part (6) and presses it against the collar (4) and on the other hand in a recess of the carrier (8) which is fixed in the housing (1) and this on the opposite of the pin Page locks.

The carrier (8), which is usually made of plastic by injection molding, consists of a central part (9) and a flap (11) connected to it by film hinges (10, 10 '). There is one for each power connection Flap required, for example for two additional connections (11 '), which, however, are identical to 11 in the further description does not need to be explained in more detail. If the flap (11) protrudes from the middle part (9), As shown in FIG. 2, one of the two parts 9 and 11 and the film hinges (10 and 10 ') is created opening through which the connection (12) extends. Another connection is designated by 12 '. The inner piece (13) of the connection (12) is used to make contact and acts in a known manner with the contact part (6) together. The electrical line is connected to the outer piece (14). The middle piece (15) is not the same width as pieces 13 and 14, for example it has outward-facing tabs (16 and 16 '). In the flap (11) of the carrier (8) is a recess (17), the contour and depth of which correspond to the middle piece (15), so that with the flap (11) placed on the middle part (9), as shown in FIG. 1, the middle piece (15) in the Carrier (8) is immovably embedded. The recess (17) could of course also be made in the central part (9) be.

The flap (11) can also have a pin (18), which extends through a hole (19) in the middle piece (15) of the connection (12) into a recess (20) of the support middle part (9) extends into it and causes the connection (12) during assembly, ie When putting on the flap (11) (in the direction of the arrow in Figure 2) it is pre-centered * It is special for assembly advantageous if the pin (18) and the recess (20] are designed so that they form a snap connection, because then the carrier (8) and connections (12) already Hold them together before inserting them into the housing (1) and handling is much easier.

The described design of the carrier (8) therefore ensures that the connections (12, 12 ') are securely fixed. achieved without the complex manufacturing that has been customary up to now.
